Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Cream of Clam Soup
Ingredients
Directions
Cook the clams
Boil the clams in their juice for 20 minutes, skimming any foam that rises to the top.
Add the minced onion and continue boiling for another 20 minutes.
Make the sauce
In a separate pot, melt the butter and stir in the flour.
Gradually add the hot milk to the butter and flour mixture.
Combine and finish
Combine the milk mixture with the clam mixture, seasoning with red pepper.
Do not cook after adding the clams; just mix well and heat through.
For a richer soup, stir in some hot cream before serving.
Strain the soup through a strainer before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Clams
- Provide the main seafood flavor and body of the soup.
- Onion
- Adds aromatic sweetness and savory depth as it cooks in the clam liquid.
- Butter
- Carries flavor and enriches the texture of the base.
- Flour
- Thickens the butter and milk into a smooth, body-giving base.
- Milk
- Forms the creamy liquid that gives the soup its smooth texture.
The step that matters
Heating after combining the milk and clams. Once the milk mixture and clams are joined, keep the heat gentle. Boiling dairy can curdle or scorch, and overcooked clams turn rubbery and tough.
Swap the onion

Fit is the average pairing score against clam, butter, flour, milk, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
